Typical response from 0 to 5000 ppm CO

Temperature compensation corrects for temperature error in the detector. Best compensationincludes both span and zero correction; span correction can be a universal correction, but zero temperaturecorrection will vary with each cell. The graph above shows error at 5,000 ppm CO
